(more)
A Mach number is used to represent the speed of objects such as airplanes. A mach number is the speed of an object moving through air or any other fluid substance divided by the speed of sound as it is in that substance. This number is useful not because it expresses the speed of an object in absolute terms like km/h or m/s, but because it uses speed of sound as a reference point, which is very useful when the speed of sound changes due to atmospheric conditions. In this ranking you can see the fastest planes ever built by man, ordered by their Mach speed.

Interestingly enough, the first attempts to incorporate a soundtrack into a movie involved synchronizing a phonograph to the images of a projector. Needless to say this process was problematic and it didn't take long for it to improve. Nowadays the musical soundtracks of films, video games, television and radio shows have sold and continue to sell millions of albums. And this is not a coincidence as many great composers like John Williams and Vangelis have placed their talent at the disposal of the Seventh Art.

There is a lot of diversity among so many species. The giraffe stands out for its height, while the elephant stands out for its weight. In the same way many stand out for their speed as we can see in this list which shows the fastest land mammals on Earth.

The growth of body hair is related to the level of androgens (a male hormone) in an individual. Due to the fact that men have higher levels of androgens than women, men tend to have more body hair than women. However the participants in this ranking have more body hair than usual. This is most likely due to a mutation in their DNA, since two of them are brothers. As you can imagine, having a lot of body hair has its advantages and disadvantages, but they at least get to show off their position on this ranking as the hairiest men on Earth.
